Wheelbuilding w/discs - spokes?

Quoted message said:

Seems like disc brakes would cause less stress on the spokes, and if the revolutions worked
before, why not again? Anything wrong with straight lacing the disc wheel front for the
light rider?

Disc brakes cause more stress on the spokes, and the entire wheel, too.

And, radial lacing + disc brakes = bad idea.

spokes in disk braked wheels get stressed more than ordinary wheels, so skinny spokes working closer
to their peak load.

it's best to stick with the 14/15/14's. i /have/ seen people build with
14/16/14's on disk wheels, but the rider was a bantam weight and the wheels were hideously out of
true inside a week.

Just to elaborate on this, rim brakes introduce no torque force to the wheel. In contrast, disc
brakes rely on the spokes to distribute the torque of stopping entirely. This adds additional stress
to the wheel, stress that a radial wheel is least able to distribute effectively. As far as spoke
choice goes, 14/15 db is the "standard" by which all other wheels are measured. Generally, you can
build a bullet-proof wheel for just about any application with these spokes. Revolutions will work
in certain applications and when built well will be fine for many applications. I think your 120lb
female will be fine with Revos and discs, but I might err on the side of caution with your other
rider and use 14/15. You should DEFINITELY use 3x (at least 2x...the weight difference is minimal
unless you're a pro rider..) and I've never personally liked alloy nipples. I'd rather use regular
brass and since you're switching to discs, I don't think weight is an issue.

Good luck,

Scott..

Gee, that's novel. To what do you attribute that? Are you claiming the center section of the spokes
_changed_ in some way during the week?

I suppose we should also avoid rims with the same color sticker as those wheels. After all,
they "were hideously out of true inside a week". I hope I don't have any wheels with the same
color sticker.

BC-<< Anyway, everyone seems to recommend 14/15 db spokes for disc wheels. Why? Seems like disc
brakes would cause less stress on the spokes, and if the revolutions worked before, why not again?

ya didn't get thoise wheels from us did ya BC(the Revs). Lots of torque at the hub on discs, 14/15
three corss is essential.

Make sure you blue loctite the 'nipples'(Rim inserts) of the 3.1 and make them TIGHT!!

Who's making them??

BC<< Finally, I have not built up a wheel with the UST 3.1s yet. How do the spoke holes work -
standard spokes or special spokes like the ksyriums?

Like the ksyriums, a threaded in insert that holds a conventional nipple, once laced, build
normally, but 14/15 3 corss is essential...

no. i'm saying that the builder didn't follow manufacturers recommendations - just like they didn't
read the book on how to build the wheel properly. laziness in one area is frequently associated with
laziness in another.
